dr. jeffrey kaplan, vice president of global health at emory university, which received these two americans touch chi, if i could begin with you. we know there are rules about how you bring out and introduce drugs like this one. but it was tried with success on two americans. back here, you understand that there are many africans suffering now who say why can't we try it as well? are the circumstances dire enough as ebola spreads and w.h.o. says it is moving faster than they can react to accelerate this process to get the serum to people there quicker? >> no doubt, jim that's the case. two americans who got it the first time in a human. this there is this assumption it worked dramatically, we don't know that because the individuals were under good care and about were getting better any watch i think we better withhold judgment that this was some sort of a miraculous turn around on the basis of this serum. i agree with you completely, the company is trying to scale up now, even with resources from the united states, from the department of health and human services, to make more of this so th

dr. kaplan, let me bring you in on this, just the timeline here, saturday august 2, that's when nancy writeboll, older by some years, 59 years old was admitted into the hospital. they were kept on a similar unit, but on opposite ends of this isolated area, as we await more information to dr. fouch chi's point, we do and should pause before we give credit to this unknown serum. >> well the drug certainly was tested and i think appropriately so. but we just don't know did they survive because they had pretty good support tiff medical care, not that we know any way to treat it but if you get fluids and are kind of brought through some of the rough parts of the disease, some people do make it. we can't really say they made it due to, if you will the success of this experimental drug. at the same time, we're going to be watching them. >> we're watching right now, i'm sorry to interrupt you, dr. bruce riber, who treated both of these patients. going to the emery staff, there were critics who said these two americans should not be allowed back into the country, emery felt confident it had the facility

dr. kent brantly you're seeing there. called his cure a miracle. missionary nancy writebol was released from the same hospital in atlanta on tuesday. want to bring in professor arthur kaplantart with nigeria and why that's so concerning. secondary contact from someone who came in through the airport. this is not supposed to happen. >> not supposed to happen. nigeria is a big, sophisticated, relatively rich country. it's got a lot of doctors. should be able to quarantine. should be able to restrict travel. should be able to educate people. if you're throwing up, if you're sick, no airport for you. so the fact that these two cases happened is troubling. it's also bothersome because there's a lot of people coming and going around nigeria and through nigeria for business. that's a place you want to have absolutely good quarantine. >> this is the big fear. all we talk about is airports, people being able to move around. i don't want to call this isolated, but this has to be a cause for greater concern because that's a major airport, and somebody gets on a plane there is not caught and ends up somewhere else, we're having a different conversation. >> that's right. it's a big hu
